I've noticed that every time I install something, rundll32.exe runs and it takes up 99% of my disk resource, which makes my computer slow. This is the command that is run:

rundll32.exe aeinv.dll,UpdateSoftwareInventory

I have to end it manually from task manager, and everything goes well even though I ended a system process.

Does anyone know what has caused this? How would I disable it?

The aeinv.dll is a dll for application compatibility. The UpdateSoft‌​wareInventory command scans your Windows for the installed applications and sends them as telemetry to Microsoft if you are part of the Customer Experience Improvement Program. Microsoft uses it to see which combination of software is used by people to minimize compatibility issues.

I had this problem for quite a time as well and didn't know what to do, until I found an answer in another forum and that helped me!

You can disable the "Program Compatibility Assistant Service", as it appears to be this service that summons the aeinv.dll,UpdateSoftwareInventory. If you want to be sure, disable the "Customer Experience Improvement Program" as well. I tested it myself and it worked for me, aeinv.dll is no longer being summoned from the depths of hell to consume my computer resources!
